25 | * SoC dynamic audio power management |
26 | * |
27 | * We can have up to 4 power domains |
28 | * 1. Codec domain - VREF, VMID |
29 | * Usually controlled at codec probe/remove, although can be set |
30 | * at stream time if power is not needed for sidetone, etc. |
31 | * 2. Platform/Machine domain - physically connected inputs and outputs |
32 | * Is platform/machine and user action specific, is set in the machine |
33 | * driver and by userspace e.g when HP are inserted |
34 | * 3. Path domain - Internal codec path mixers |
35 | * Are automatically set when mixer and mux settings are |
36 | * changed by the user. |
37 | * 4. Stream domain - DAC's and ADC's. |
38 | * Enabled when stream playback/capture is started. |
